Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a leakage prevention and plugging device for wall and column formworks. Background Technique

[0002] At present, in the construction field such as housing construction, there is a phenomenon that the contact position between the wall and column formwork and the lower floor slab is not closely attached, which often leads to different degrees of leakage during the concrete pouring process. In the face of this phenomenon, root rot and large-area leakage often occur during the construction process. Therefore, before the concrete pouring, a leakage prevention and plugging device for wall and column formworks is usually used to plug the gaps.

[0003] When the existing leakage prevention and plugging devices for wall and column formworks are in use, most of them are prone to displacement after being treated by vibrating rods for concrete, and most of the leakage prevention and plugging devices for wall and column formworks do not have an automatic correction function. As a result, during the concrete pouring process, the concrete is likely to flow out from the displaced gap, thereby reducing the sealing effect of the leakage prevention and plugging device for wall and column formworks.

[0004] Combining the above problems, we will find that when the existing leakage prevention and plugging devices for wall and column formworks are in use, it is very difficult to avoid the above-mentioned problems at the same time. And even if it can be solved, it needs to be solved by cooperating with external tools, thus unable to achieve the desired effect.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figures 1 - 5 , the present invention provides a technical solution: a wall column formwork anti-leakage plugging device, including an installation box 1, a plugging mechanism 2 is arranged above the installation box 1, the plugging mechanism 2 includes a sealing block 201, an airbag 202 is fixedly installed on the bottom surface of the sealing block 201, a sealing gasket 203 is arranged below the airbag 202, and both the sealing gasket 203 and the sealing block 201 are made of rubber material, so that both of them have good extension effects; A correction component 3 is arranged on the back of the installation box 1.

[0023] As a further limitation of the correction component 3 of the present invention, the correction component 3 includes a magnetic block 301. The magnetic block 301 is fixed to the template by an expansion bolt. The magnetic block 301 is located above the sealing block 201. An electromagnet 302 is fixedly installed on the outer surface of the installation box 1. The back surface of the electromagnet 302 is in contact with the front surface of the magnetic block 301. By using the attraction between the electromagnet 302 and the magnetic block 301, the installation box 1 is fixed to the template. At the same time, the installation box 1 is fixed to the ground by cooperating with the expansion bolt, thus ensuring the stability of the installation box 1. Two sets of telescopic columns 303 are fixedly installed on the back surface of the electromagnet 302. The telescopic ends of the two sets of telescopic columns 303 are jointly fixedly installed with a connecting plate 304. A magnetic plate 305 is fixedly installed on the front surface of the connecting plate 304. By using the repulsive force between the magnetic plate 305 and the electromagnet 302, the magnetic plate 305 is made to push the sealing block 201 to closely fit the gap of the template. A pressure sensing sheet 306 is fixedly installed on the back surface of the connecting plate 304. The back surface of the pressure sensing sheet 306 is fixedly connected to the front surface of the sealing block 201. A micro air pump 307 is fixedly installed on the inner bottom wall of the installation box 1. The air inlet end of the micro air pump 307 is fixedly communicated with a connecting pipe 308. One end of the connecting pipe 308 far from the micro air pump 307 penetrates to the outside of the installation box 1. The air outlet end of the micro air pump 307 is fixedly communicated with a delivery pipe 309. One end of the delivery pipe 309 far from the micro air pump 307 penetrates to the inside of the air bag 202. An air outlet pipe 310 is fixedly communicated with the front surface of the air bag 202. A solenoid valve 311 is fixedly communicated with the outer surface of the air outlet pipe 310. A current controller 312 is fixedly installed on the front surface of the installation box 1. By adjusting the current input to the electromagnet 302 through the current controller 312, the magnetism of the electromagnet 302 is adjusted. By providing the correction component 3, the worker fixes the magnetic block 301 on the template. After that, when the vibrator vibrates the concrete, the pressure detected by the pressure sensing sheet 306 will increase, so that by increasing the magnetic force of the electromagnet 302, the electromagnet 302 and the magnetic block 301 attract each other, making the electromagnet 302 more firmly fixed at the template. At the same time, by using the repulsive force between the electromagnet 302 and the magnetic plate 305, the sealing block 201 is made to fit more closely with the gap, thus avoiding the phenomenon of concrete leakage.

[0024] Please refer to Figure 3 As shown in the figure, a storage battery 313 is fixedly installed on the front surface of the installation box 1. The storage battery 313 is electrically connected to electronic components such as the electromagnet 302, the pressure sensing sheet 306, the micro air pump 307, the solenoid valve 311 and the current controller 312 through wires. The installation of the storage battery 313 can provide electric energy for the electrical equipment of the device, so that the device is not restricted by the length of the wire.

[0025] Please refer to Figure 1, a protective box 314 is fixedly installed on the front of the installation box 1, and a protective cover 315 is movably hinged to the front of the protective box 314. The installation of the protective box 314 and the protective cover 315 plays a role in safely protecting the battery 313 and the current controller 312, thus preventing the two from being collided from the outside.

[0026] The specific implementation manner of this embodiment is as follows: When in use, the worker first fixes the magnetic block 301 on the formwork, and then inserts the gasket 203 into the gap between the formwork and the ground, and uses the attraction force between the electromagnet 302 and the magnetic block 301 to fixedly connect the installation box 1 to the formwork. Then, the installation box 1 is fixed to the ground by expansion bolts, further increasing the stability of the installation box 1. When the worker vibrates the concrete with a vibrator, the concrete squeezes the sealing block 201, so that the pressure received by the pressure sensing piece 306 increases, and the pressure sensing piece 306 transmits a signal to the current controller 312, causing the current controller 312 to increase the input current of the electromagnet 302, so that the magnetic force of the electromagnet 302 increases, and then the attraction force between the electromagnet 302 and the magnetic block 301 increases. At the same time, the repulsive force between the electromagnet 302 and the magnetic plate 305 is increased, so that the electromagnet 302 is more firmly adsorbed on the formwork. At the same time, through the repulsive force, the connecting plate 304 pushes the sealing block 201 to squeeze the formwork, so that the sealing block 201 better fits the outer surface of the gap, avoiding the phenomenon of concrete leakage.

[0027] Embodiment 2: Please refer to Figure 4 and Figures 6 - 8 , the present invention provides a technical solution: a wall column formwork anti-leakage plugging device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. An expansion assembly 4 is arranged inside the installation box 1.

[0028] As a further limitation of the expansion component 4 of the present invention, the expansion component 4 includes two connecting springs 401. One end of each connecting spring 401 away from the sealing block 201 is fixedly connected to the inner wall of the installation box 1. The two ends of the connecting springs 401 close to the sealing block 201 are jointly fixedly installed with a moving block 402. The back surface of the moving block 402 is fixedly connected to the front surface of the sealing gasket 203. A shape memory alloy wire 403 is fixedly installed on the inner wall of the sealing gasket 203. Two fixing springs 404 are fixedly installed on the inner wall of the installation box 1. The two ends of the fixing springs 404 close to the moving block 402 are jointly fixedly installed with a pushing block 405. A connecting block 408 is fixedly installed on the right side surface of the pushing block 405. A connecting shell 406 is fixedly installed on the inner bottom wall of the installation box 1. The connecting block 408 is slidably connected to the inside of the connecting shell 406. A shape memory alloy block 407 is arranged inside the connecting shell 406. The upper surface of the shape memory alloy block 407 and the outer surface of the shape memory alloy wire 403 are jointly fixedly installed with a heating resistance wire 409. Both the shape memory alloy wire 403 and the shape memory alloy block 407 are made of nickel-titanium-based shape memory alloy. Therefore, when both of them are heated, they will expand, and when cooled, they will return to their original state. By providing the expansion component 4 and utilizing the phenomenon that the shape memory alloy wire 403 and the shape memory alloy block 407 expand when heated, the sealing gasket 203 stuck at the gap expands, thereby further avoiding the phenomenon of concrete leakage. At the same time, the pushing block 405 is used to push the moving block 402 to move, thereby avoiding the phenomenon that the position of the sealing gasket 203 shifts during concrete vibration, and further ensuring the good sealing performance of the device.

[0029] Please refer to Figure 7 and Figure 8 As shown in the figure, a sliding block 410 is fixedly installed on the bottom surface of the moving block 402. A sliding groove 411 is formed on the inner bottom wall of the installation box 1. The sliding block 410 is slidably connected to the inside of the sliding groove 411. The installation of the sliding block 410 and the sliding groove 411 serves to limit the movement track of the moving block 402, thereby avoiding the phenomenon that the moving block 402 deviates from the movement track during movement, and further ensuring the stability of the moving block 402.

[0030] Please refer to Figure 8 As shown in the figure, two telescopic rods 412 are fixedly installed on the right side surface of the pushing block 405. The right end of each telescopic rod 412 is fixedly connected to the inner wall of the installation box 1. The installation of the telescopic rods 412 serves to limit the movement track of the pushing block 405, thereby ensuring the stability of the movement of the pushing block 405.

[0031] The specific implementation of this embodiment is as follows: When the pressure received by the pressure sensing sheet 306 increases, the electrothermal resistance wire 409 is used to heat the shape memory alloy wire 403 and the shape memory alloy block 407 respectively, so that both of them expand when heated. Due to the expansion of the shape memory alloy wire 403 when heated, the sealing gasket 203 expands inside the gap, thereby increasing the area of the sealing gasket 203, making the sealing gasket 203 fit more closely with the gap. At the same time, when the shape memory alloy block 407 expands due to heat, it will push the connecting block 408 to move to the left, so that the connecting block 408 pushes the pushing block 405 to move. At the same time, the fixing spring 404 is stretched, and then the pushing block 405 pushes the moving block 402 to move towards the side close to the sealing gasket 203, so that the sealing gasket 203 receives a pressure opposite to that of the concrete, thus avoiding the phenomenon of position deviation of the sealing gasket 203, and further ensuring the good sealing performance of the device.

[0032] Example 3: Please refer to Figure 1 , Figure 4 , Figure 6 and Figures 8 - 10 , the present invention provides a technical solution: a leakage prevention and plugging device for wall column formwork. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. An expansion component 5 is arranged inside the installation box 1.

[0033] As a further limitation of the expansion component 5 of the present invention, the expansion component 5 includes a storage tank 501. The bottom surface of the storage tank 501 is fixedly connected to the outer surface of the installation box 1. A load-bearing block 502 is slidably connected inside the storage tank 501. An installation frame 503 is fixedly installed on the outer surface of the installation box 1. An electric push rod 504 is fixedly installed on the inner top wall of the installation frame 503. A fixed block 505 is fixedly installed at the telescopic end of the electric push rod 504. A pressure sensor 506 and two installation springs 507 are fixedly installed on the bottom surface of the fixed block 505. The bottom ends of the two installation springs 507 are jointly fixedly installed with a pressing block 508. The bottom surface of the pressing block 508 is in contact with the upper surface of the load-bearing block 502. The pressure applied by the pressing block 508 to the load-bearing block 502 is detected by the pressure sensor 506. Thus, when the pressure between the two is small, the pressure applied is increased through the electric push rod 504. The model of the pressure sensor 506 is TE-SMI-7000. A connecting rod 509 is fixedly installed on the left side surface of the pushing block 405. A rack plate 510 is fixedly installed at the left end of the connecting rod 509. A rotating shaft 511 is rotatably connected inside the installation box 1. A connecting gear 512 and a first conical wheel 513 are respectively fixedly installed on the outer surface of the rotating shaft 511. The outer surface of the connecting gear 512 is meshed with the upper surface of the rack plate 510. A bearing seat 514 is fixedly installed on the inner bottom wall of the installation box 1. A rotating shaft 515 is rotatably connected inside the bearing seat 514. A second conical wheel 516 is fixedly installed at one end of the rotating shaft 515. The outer surface of the first conical wheel 513 is meshed with the outer surface of the second conical wheel 516. A fixed pipe 517 is fixedly communicated with the bottom surface of the storage tank 501. One end of the fixed pipe 517 away from the storage tank 501 penetrates into the inside of the sealing gasket 203. A valve 518 is fixedly communicated with the outer surface of the fixed pipe 517. The other end of the rotating shaft 515 is fixedly connected to the outer surface of the valve 518. A water pump 519 is fixedly installed on the inner bottom wall of the installation box 1. The water inlet end of the water pump 519 penetrates into the inside of the sealing gasket 203. The water outlet end of the water pump 519 is fixedly communicated with a circulation pipe 520. One end of the circulation pipe 520 away from the water pump 519 penetrates into the inside of the storage tank 501. By providing the expansion component 5, when the shape memory alloy block 407 expands, by opening the valve 518, the liquid inside the storage tank 501 enters into the inside of the sealing gasket 203 under the action of the load-bearing block 502 and the pressing block 508, so that the sealing gasket 203 can further fit the gap, further increasing the good sealing performance of the device and avoiding the phenomenon of concrete leakage.

[0034] Please refer to Figure 10 Two telescopic shafts 521 are fixedly installed on the bottom surface of the fixed block 505. The telescopic end of each telescopic shaft 521 is fixedly connected to the upper surface of the pressing block 508. The installation of the telescopic shafts 521 plays a role in restricting the movement track of the pressing block 508, thus ensuring the stability of the pressing block 508.

[0035] Please refer to Figure 4 、 Figure 6 、 Figure 8 and Figure 9 , a sliding plate 522 is fixedly installed on the bottom surface of the rack plate 510, and a slide rail 523 is provided on the inner bottom wall of the installation box 1. The sliding plate 522 is slidably connected inside the slide rail 523. The installation of the sliding plate 522 and the slide rail 523 restricts the movement track of the rack plate 510, thereby ensuring the stability of the movement of the rack plate 510.

[0036] The specific implementation manner of this embodiment is as follows: During the process of pushing the pushing block 405 to move, the connecting rod 509 is driven to move to the left, so that the connecting rod 509 pushes the rack plate 510 to move, and then the rack plate 510 drives the connecting gear 512 to rotate, so that the connecting gear 512 drives the rotating shaft 511 and the first conical wheel 513 to rotate, so that the first conical wheel 513 drives the second conical wheel 516 to rotate, and then the second conical wheel 516 drives the rotating shaft 515 and the valve 518 to rotate, and then the fixed pipe 517 is opened, so that the liquid inside the storage tank 501 enters the inside of the sealing gasket 203 under the action of the load-bearing block 502, so that the sealing gasket 203 expands further, so that the sealing gasket 203 fits with the gap. At the same time, when the pressure sensor 506 detects that the pressure applied by the extrusion block 508 to the load-bearing block 502 is small, the power provided by the electric push rod 504 drives the fixed block 505 to move downward, so as to maintain the pressure applied by the extrusion block 508 to the load-bearing block 502, so as to avoid the phenomenon of liquid backflow caused by the concrete applying a large pressure to the sealing gasket 203. After the concrete solidifies, the electric heating resistance wire 409 is turned off, so that the shape memory alloy wire 403 and the shape memory alloy block 407 cool down and return to their original state, so that the fixed pipe 517 is closed, and then the liquid inside the sealing gasket 203 is pumped back by the power provided by the water pump 519, which is convenient for subsequent use.

[0037] Specifically, when in use: First, the worker first fixes the magnetic block 301 on the template. Then, the worker inserts the gasket 203 into the gap between the template and the ground, and uses the attraction between the electromagnet 302 and the magnetic block 301 to fixedly connect the installation box 1 to the template. Then, the installation box 1 is fixed to the ground by expansion bolts, further increasing the stability of the installation box 1. When the worker vibrates the concrete with a vibrator, the concrete squeezes the sealing block 201, so that the pressure received by the pressure sensing piece 306 increases. As a result, the pressure sensing piece 306 transmits a signal to the current controller 312, causing the current controller 312 to increase the input current of the electromagnet 302, so that the magnetic force of the electromagnet 302 increases. Furthermore, the attraction between the electromagnet 302 and the magnetic block 301 increases, and at the same time, the repulsive force between the electromagnet 302 and the magnetic plate 305 increases, making the electromagnet 302 more firmly adsorbed on the template. At the same time, through the repulsive force, the connecting plate 304 pushes the sealing block 201 to squeeze the template, so that the sealing block 201 better fits the outer surface of the gap.

[0038] Then, when the pressure received by the pressure sensing piece 306 increases, the electrothermal resistance wire 409 is used to heat the shape memory alloy wire 403 and the shape memory alloy block 407 respectively, so that the two expand when heated. Due to the heat expansion of the shape memory alloy wire 403, the gasket 203 expands inside the gap, thus increasing the area of the gasket 203 and making the gasket 203 fit more tightly with the gap. At the same time, when the shape memory alloy block 407 expands due to heat, it pushes the connecting block 408 to move to the left, so that the connecting block 408 pushes the pushing block 405 to move. At the same time, the fixing spring 404 is stretched. Furthermore, the pushing block 405 pushes the moving block 402 to move toward the side close to the gasket 203, so that the gasket 203 receives a pressure opposite to the concrete, thus avoiding the phenomenon of the gasket 203 shifting in position, and further ensuring the good sealing performance of the device. Furthermore, during the process of driving the moving block 405 to move, the connecting rod 509 is driven to move to the left, so that the connecting rod 509 drives the rack plate 510 to move, and then the rack plate 510 drives the connecting gear 512 to rotate, so that the connecting gear 512 drives the rotating shaft 511 and the first conical wheel 513 to rotate, so that the first conical wheel 513 drives the second conical wheel 516 to rotate, and then the second conical wheel 516 drives the rotating shaft 515 and the valve 518 to rotate, and then the fixed pipe 517 is opened, so that the liquid inside the storage tank 501 enters the inside of the sealing gasket 203 under the action of the load-bearing block 502, so that the sealing gasket 203 expands further, so that the sealing gasket 203 fits with the gap. At the same time, when the pressure sensor 506 detects that the pressure exerted by the extrusion block 508 on the load-bearing block 502 is small, the power provided by the electric push rod 504 drives the fixed block 505 to move downward, so as to maintain the pressure exerted by the extrusion block 508 on the load-bearing block 502, so as to avoid the phenomenon that the concrete exerts a large pressure on the sealing gasket 203 and the liquid flows back. When the concrete solidifies, the electric heating resistance wire 409 is turned off, so that the shape memory alloy wire 403 and the shape memory alloy block 407 cool down and return to their original state, so that the fixed pipe 517 is closed. Then, the power provided by the water pump 519 is used to pump the liquid inside the sealing gasket 203 back, so as to facilitate subsequent use.
